The Register has a very interesting story on Googlewashing.
What is Googlewashing?
It describes a new phenomenon whereby search results on Google can be influenced by a disproportionately small number of influential parties, in this case bloggers.
This is a very important illustration of why the online environment offers some different challenges in communicating effectively.
Google is the de facto research portal for the Internet. Yes there are other search engines and directories, but Google is by far the most popular.
Now, if the prominent ranking for a particular search term has more to do with what bloggers have written about it, rather than what publications have written about it, then there is new tactical section in your PR plan.
Bloggers are not journalists, but it would seem they do have a role to play in online promotion.
